4.3 Selecting the system control parts
Using the system controller (SC) together other than LM ADAPTER allows connecting operation. Some
rules to be observed for this purpose are introduced below.
4.3.1 Master controller and slave controller
When LM ADAPTER is used together with other system controller inside a system under own control, it is
essential to set a slave SC(requiring a DIP-SW change). In this case, set it so that the control range of LM
ADAPTER is included within the control range of the system controller (air conditioner) which is to be the
master SC.

① When using together the system controller that can set to prohibit the local remote controller operation,
make the controller for setting of operation prohibit one unit, either LM ADAPTER (BMS) or the system
controller.
② Operation prohibit can not be applied to other system controllers by LM ADAPTER (from BMS)
③ Although air conditioners can not be operated by the local remote controller of which operation is being prohibited,
they can be operated by LM ADAPTER (BMS) or other system controllers.

(2) Emergency stop
The emergency stopping of LM ADAPTER stops all air conditioners together, however it does not set the
operation prohibit of the local remote controller allowing the operation from other system controller or local
remote controller. To prohibit operation from the local remote controller, therefore, set it by entering
[Request Collective Local Prohibit] (collective).
*Operating to run during emergency stopping only results in immediate stopping.
(3) Operation mode
In the case of cooling/heating selectable models of CITY MULTI, the operation mode will be determined by
the principle of the "Priority for former pressing."
Under the circumstance, a same command should be
issued to all indoor units within a same refrigerant system to change the operation mode.

5. Design and Operation of LONWORKS System
This section introduces the mechanism, function and operating method of LM ADAPTER in configuring the
system of LONWORKS network by LM ADAPTER. As the operating method shown here represents just one
of the examples, you are kindly requested to carry out your designing to meet the system configuration or
operation in the actual system.
5-1 Constructing the LONWORKS network
The flow of installation procedure for LONWORKS network is shown below.
Step 1: Addressing (to determine the address of each node)
Step 2: Binding (to connect network variables)
Step 3: Configuration (for optimum service of each connection, adjustment of
re-transmission frequency and interval)
(1) Addressing
An address is assigned to each node (equipment applicable to LONWORKS) on the LONWORKS network.
Set this address by using the install tool. Setting by using LM ADAPTER is not necessary.
(2) Binding
The network variables between each node should be related with the exclusive tool like LonMaker for
Windows ® or the like.
(3) Configuration
For the configuration property of LM ADAPTER, the initial value was set at factory shipment. The set value
may be changed depending on the configuration or operation of the network.
Node Address = 1
Node Address = 2
BMS
Indoor [1]
Binding of network variables
18
5.2 Function relating to installing
(1) Service pin (Service switch)
The service pin is used at the installation of LONWORKS network.
Pressing the service pin sends out the service pin-message (control message including Neuron ID and
Program ID) to the network.
(2) Service LED
The service ID indicates the present state of the product.
In the case of LM ADAPTER under the shipment state (Non-configured state), the service LED is blinking.
(3) WINK
Upon receipt of the WINK message from the LONWORKS network, LM ADAPTER blinks the maintenance
LED 001 for about 10 seconds.
(4) Commission
After completing the binding, the set detail is reflected on the node. Doing this way allows communication
between the nodes on the LONWORKS network.
(5) XIF
To design the LONWORKS network, the configuration information of each node, interface (network
variables), etc. are required. When the product is already in your hand, such information can be obtained from
the LONWORKS network. Without the product, however, you may get it from XIF (eXternal Interface File)
locating the interface information of the product.

5.3 Operation at power recovery
5.3.1 Outline of LM ADAPTER operation
After the power source is applied (the same as the power recovery after instantaneous power stop/power
failure), LM ADAPTER requires a time for initialization to collect the connection and operation state of air
conditioners up to 50 sets to be controlled. As the operation timing differs depending on the setting of
configuration property, you are kindly requested to carry out designing to meet the system operation.

(1) Setting of Neuron Chip communication start time
The communication start timing of NC can be set through “Communication Timing 【nciSet_1】”.
① "initialize"
Upon completion of the connection between LM ADAPTER and air conditioner, NCstartsoperation. Up to
this time, NC will not reply (even without returning of Ack).
This operation is specifically used to acquire the state of air conditioners by Poll (Fetch)demand.
② "setting time"
Synchronized with the shortest time among the set times of the configuration property below, NC starts
operation. Up to this time, NC will not reply (even without returning of Ack).
This operation is specially used to acquire the state of air conditioners by event (at changing) output.

Initialize Start Time
The timing to start the initial output is set.
【nciInitStartTm】
To match the image of the operation information on air conditioners held by BMS and
that of the actual operation status, LM ADAPTER automatically outputs the status of
the air conditioners after power recovery.
21
(3) Setting to match images
1
The state of an air conditioner before power failure and after power recovery may differ sometimes . In
such case, the operation state of the air conditioner held by the BMS differs from the actual operation state of
the air conditioner. In order to match the image after power recovery, LM ADAPTER can be set enabling the
initial output to match the image at a time when a certain time has elapsed after power recovery.

5.4 Response restrictions on Poll (Fetch) demand
Upon receipt of Poll (Fetch) demand from the BMS, LM ADAPTER responses with the latest value of the
corresponding variable.
As the operation status being held will be responded at power shutdown due to air conditioner inspection or
communication error caused by the disconnection of M-NET transmission line, the error cannot be judged by
the BMS.
When the present data being held is uncertain as is in such case, LM ADAPTER can be set so that error
generation can be judged easily by suppressing the response against Poll (Fetch) demand.
①Suppressing the response of unconnected indoor units.
②Suppressing the response of indoor units unable to communicate.
This setting is to follow the configuration property below.

5.5.3 Function allowing operating/setting at local side
When using a remote controller together to operate air conditioners locally by user, the same function can be
operated/set at both the master system side and the local side. In this case, the "Priority is given to the later
pressing" is a principle. Please carry out to configure the LONWORKS system taking the following into
consideration.
(1) Disagreement of state
Problem
Disagreement of state may occasionally be detected when setting is changed by the local
side including the local remote controller after operating/setting of the BMS.
Measure taken by BMS side
Avoid detecting for the disagreement of the state.

5.8.1 Trouble/alarm monitoring by network variables
(1) Trouble and alarm of air conditioner - - - ①,③
Air conditioning equipment in trouble will be informed to the BMS by the network variables via LM ADAPTER.
In case when the local remote controller or system controller is installed, the detail of the trouble will be
displayed.
Detecting method of trouble
- Trouble of indoor unit : Error output from individual indoor unit
- Trouble of outdoor unit : Error output from all indoor units within a same refrigerant system
(2) Communication fault of M-NET (including power failure) - - - ②
When the communication (M-NET) between LM ADAPTER and air conditioner is disabled, LM ADAPTER
monitors the communication with the air conditioner for a certain time, and informs you about a
communication error if abnormality is detected.
Detecting method of M-NET communication error
- Network variables (collective for all indoor units) exclusive for communication error
- Response to Polling (by “Effective PollFetch 【nciPollFetch】”)
30
(3) Resetting of trouble/alarm
The resetting method differs depending on the equipment generating trouble/alarm.
Trouble of indoor unit
Switches over the indoor unit in trouble from [Run] to [Stop].
Trouble of outdoor unit
Switchovers all indoor units in the refrigerant system from [Run] to [Stop].
5.8.2 Health check of LM ADAPTER - - - ④,⑤
Several factors can be considered as the cause to disable the communication of the master system with LM
ADAPTER. Depending on the function of the BMS or the system configuration, conduct health check (to judge
the life) by combining each detecting method.
(1) Detection by Node Object
The Node Object is an exclusive variable to conduct health check (to judge the life) on LM ADAPTER. This is
effective when the application of LM ADAPTER is crashed under the condition allowing LON communication,
or to detect the recovery timing of power failure.
The node object uses the input variable 【nviRequest】 and output variable 【nvoStatus】 in a pair. The
output variable returns the value corresponding to the requested value when only the input variable is
renewed. The response can be performed if the application is working regardless of the status of the local
side (M-NET).
(2) Detection by effectuation of communication
When Ackd is used as the communication service of LON communication, the fault of LON communication
can be monitored by the presence of Ack.
However for the generating spot of the communication error, it is
required to judge comprehensively taking the communication status of other node into consideration.
5.9 Emergency stop
In the case when air conditioners are stopped (emergency stop) collectively, it is considered that the
communication with the master system may not be performed after stopping. For this reason, the present
status will be maintained until “Effective Time_1【nciEffectTm_1】” has passed once emergency stop was
received. Even after releasing the emergency stop, the air conditioner will continue to stop unless receiving
the run request.
